Maybe I've already replaced a #RaspberryPi5 CPU before.

But today was the first time I replaced a Secure Boot locked CPU on a Pi 5.

And that's a whole different story - after I replaced a CPU Pi blinked a 1-2 code - "SD card overcurrent detected". Weird.

I tried to restore #EEPROM from a Micro SD - it flashed 3-2 - "SPI EEPROM is write protected".

I soldered another CPU. Same.

I replaced #RP1. Same.

Turns out it was EEPROM.

Hi guys.

Have these chips on Orange Pi 5, but can’t find them neither in the schematic (https://drive.google.com/file/d/1Wsp-Q7IyG0Ky_W-z1n5oXcFG4oqIbtOb/view) nor by the chip markings.

Those are tiny bga chips marked as D25DH 6QR73 or D3FEH 68S53.

They are located under the CPU, so must be related.

I also noticed that these same chips on the same model of Orange Pi have different markings but in a similar fashion.

Thanks a lot - as always.

Usiogope kazi ama #ProgrammingSkills😢! Zaidi na kunakili data iliyoandaliwa, zana muhimu unahitaji kwanza, ni kujiamini! Hakuna elimu ya shule inayohitajika🥺!
Pata zana inayoweza kusoma, kuandika data, kisha anza kazi, #HapaUjanjaTu 🤷‍♂️! Popote ulipo, nadhani umeona aina ya mtu yeyote, ghafla anageuka kua mtaalamu

Something new on the bench - Raspberry Pi 400. This one had a broken micro SD card latch, so I had to replace the slot with a brand new one. Luckily I bought a few for a Jetson Nano back in a day and they are exactly the same ✅.

Then - as always - I ran a stress test and my god this thing has amazing cooling - that internal heatsink is the best mechanism I've ever seen on a Raspberry Pi - 40°C at max load. Wow 🤩.
